Problems solved by technology

Although the traditional hollow shaft is lighter in weight when ensuring the same torque transmission as the solid shaft, it occupies too much volume and has higher requirements for cooperation with other parts.
And the hollow shaft with smaller shaft wall thickness has weak torsion resistance, and it is easy to lose stability when carrying the load.

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0023] A hollow shaft with spider-like ribs, characterized in that it comprises a hollow shaft 1 and a spider-like rib 2, the spider-like ribs 2 are placed in the inner cavity of the hollow shaft 1, and the hollow shaft 1 and There are multiple cavities 3 between the spider web-shaped reinforcing ribs 2 , and there are multiple cavities 3 inside the spider web-shaped reinforcing ribs 2 .

[0024] Preferably, the hollow shaft 1 is integrated with the spider web-shaped reinforcing rib 2 .

[0025] Preferably, the hollow shaft 1 and the spider web-shaped reinforcing rib 2 are produced by an additive manufacturing process.

[0026] Preferably, the cross-section of the spider web-shaped reinforcing rib 2 is spider web-shaped, and the cross-section includes at least two concentric regular hexagons 20...

Abstract

The hollow shaft comprises a hollow shaft body and the cobweb-shaped reinforcing ribs, the cobweb-shaped reinforcing ribs are arranged in an inner cavity of the hollow shaft body, a plurality of cavities exist between the hollow shaft body and the cobweb-shaped reinforcing ribs, and a plurality of cavities exist in the cobweb-shaped reinforcing ribs. The occupied volume of the hollow shaft can be reduced, and meanwhile the bearing capacity is improved.

Description

technical field [0001] The invention relates to the technical field of hollow shafts, in particular to a hollow shaft with cobweb-like reinforcing ribs. Background technique [0002] As a mechanical part that transmits torque and bending moment, the shaft is widely used in transmission machinery. Although the traditional hollow shaft is lighter in weight when ensuring the same torque transmission as the solid shaft, it occupies too much volume and has higher requirements for cooperation with other parts. Moreover, the hollow shaft with a small shaft wall thickness has a weak torsion resistance, and it is easy to lose stability when carrying a load. In order to take into account the advantages of both the small volume of the solid shaft and the small mass of the hollow shaft, a hollow shaft with a new structure is required. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention aims to provide a hollow shaft with spider web-s...
